US 4,961,036 A · System for controlling a working shaft

Abstract

The inventive system for controlling a working shaft includes a layout for the time to number conversion, wherein a divider is provided to divide with use of a pulse rate outputted from the memory storage, and the shaft driver is operated by output from such a divider and is thereby controlled with use of the data stored in the memory storage. Concurrently, by introducing the counter outputs indicating the time scaling into the addresses of a memory sector, the memory sector is arranged to output varying speed data corespondent to the time scaling data. Thereby trailing actions of the working shaft to trace a given locus are determined by data stored in the memory storage, which enables a complex real time control to be feasible by the inventive simple control system, wherein, as required, a change in the control specification is simply made by a change of data in the memory storage.

Dependent claims

A system for controlling a working shaft, which comprises:

a counter fed with clock signals to work as reference timing for actions in downstream;
a memory sector, having addresses accessible to output from said counter;
a divider connected to said memory sector and enabled to divide the clock signals with use of output from the memory sector;
a shaft driver to control the working shaft with a speed relative to output from the divider;
wherein said memory sector is priorly stored with data on speed operative to the shaft to be controlled.
